Why do some ethnic minorities have the same surnames as Han people?

I don't know about other nationalities. I'm from Zhuang nationality, so let's talk about the origin of Zhuang surname.

Ancestors of Zhuang nationality (Luo Yue, Ou, etc. ) No last name. The Vietnamese have no surname, only a single name. According to Records of the Emperor Wu of the Han Dynasty, Chi Yihou, a Vietnamese, sent Yelang soldiers to Jiang Kehe and wrote "The Legacy of Chi Yihou" in Panyu, indicating that Chi Yihou was a Vietnamese with no surname. "Historical Records Biography of Nanyue Weituo": "Guiyi Yue Houyan is General Gechuan, away from Lingling and out of water; A is the next general and the next Cangwu. " Yan and Jia are both Hou Guiyi, both generals of the Vietnamese army who pacified South Vietnam, and both have only first names but no surnames. It has a long history that Vietnamese people have a single name but no surname. For example, according to the general examination of the literature, "The men and women born in Liao Manchu are called' Amoy Beggar' and' A Yi'.

The earliest record of the ancestors of Zhuang nationality by Han people is Xu Yige. "Huainanzi Human Training" records: Qin Jun "failed to relax his armor for three years, which made the supervisor unable to adjust his salary. He also led a soldier to dig canals and open grain routes to fight against the Vietnamese. Kill Xi Yujun and translate Vae. " After Qin Shiwang conquered Lingnan, China surname culture was gradually accepted by Vietnamese aristocrats, and China surnames such as Lv Jia, Prime Minister of South Vietnam, appeared. But ordinary people still don't have surnames.

After thousands of years of Han culture in Vietnam, Zhuang ancestors began to have surnames, which are generally divided into the following sources:

1. Generally, the poor take the surname of the owner (tribal leader). For example, in the Tang Dynasty, when Huang Dong was strong, the villagers were naturally surnamed Huang, and in the Song Dynasty, the villagers were naturally surnamed Nong. The surname of Dongzhu (tribal leader) is often the result of accepting China culture, so it is not surprising that Zhuang and Han people have the same surname.

2. With the increasing acceptance of China culture by Zhuang people, and a large number of Han people moving to Zhuang areas, Zhuang people have a wider choice of surnames. Generally speaking, some people accept the surnames of Han officials, some accept the surnames of Han teachers (masters) and some accept the surnames of Han celebrities. Some accept the surnames of Han immigrants, some integrate Han nationality into Zhuang nationality, and bring Han nationality surnames into Zhuang nationality.

3. Historically, there was no unified writing for Zhuang people. Surnames are recorded in Chinese characters, giving people the same impression as Han people. Actually, they are just transliteration. Many Zhuang people's surnames are the same as the Chinese characters used by Han people, but their meanings are completely different. For example, "Wei" is the most popular surname of Zhuang nationality, which means "buffalo"; "Cen" is the chopping block, and "agriculture" means "forest".
